Elf-like priest, possibly? (6)
I believe the answer is:
sprite
'elf' is the definition.
(I've seen this before)
'priest possibly?' is the wordplay.
'possibly?' indicates an anagram (I've seen 'possibly' mean this).
'priest' is an anagram of 'SPRITE'.
'like' is the link.
(Other definitions for sprite that I've seen before include "Pet, sir, could be a goblin" , "sports car" , "Naiad" , "Brownie" , "Elf, fairy" .)
